Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169970, here are decompositions:

13 + 169957 = 169970
19 + 169951 = 169970
37 + 169933 = 169970
61 + 169909 = 169970
79 + 169891 = 169970
127 + 169843 = 169970
139 + 169831 = 169970
181 + 169789 = 169970

Showing the first eight; more decompositions exist.
